You Measured the Height—But Did You Calculate the Fall?
June, 2025 Sudbury, Ontario - Working at heights is common in many industries, whether on roofs, scaffolding, ladders, or other raised work platforms. However, working at height presents a major workplace hazard–the risk of falling. Falls from elevation can result in serious injuries and fatalities. In Canada, over 44,000 workers suffer fall-related injuries annually. Understanding fall distance is crucial for implementing proper fall prevention and protection measures.
Fall distance refers to the total vertical distance a worker travels during a fall before a fall arrest system stops the fall. The greater the fall distance, the higher the risks and potential impact forces on the worker's body. Factors such as the height of the elevated work surface, any pendulum-like swing during the fall, and even reaction time to activate safety gear can all increase fall distance.
Precautionary measures should be taken to minimise total fall distance. Proper calculation of potential fall distance can inform the appropriate selection and configuration of fall protection systems. For example, fall arrest systems must be rigged to ensure adequate clearance below the work surface to arrest the fall before the worker strikes the ground or other objects. Accurately estimating fall distance can be a matter of life, serious injury, or even in some cases, death.
